ELECTRIC LAMP GUARD Filed Feb. 15, 1932 INVENTOR ATTOR N EY PatentedJan, 3, 1933 UNITED STATES ROBERT LEE GRANT, JR, 0E rnxanmnnnxnnsns,ssienon: 'ro "BESSIE. soo'r'r BOISSEAU GRANT, or TEXARKANA,ARKANSASELECTRIC LAMP strait n The invention relates to an electric light bulbguard and more particularly to a com bined guard and light shade forelectric light bulbs.

The primary object of the invention is the provision of a device of thischaracter wherein on the mounting thereof upon an electric light socketsame will serve to protect the bulb and also will function as a shadefor the light issued by the bulb, the device being adjustable to varythe shading of the light at the option of the user of such device.

Another object of the invention is the provision of a device of thischaracter, wherein a shading shutter is movably supported in a novelmanner within the guard of a semibulbous reflector so that on adjustmentof the shutter the light rays from'a bulb of the electric type can beshut off or diminished accordingly to the requirement of the user of thelight, the device in its entirety being of novel form.

A further object of the invention is the provision of a device of thischaracter which constitutes an attachment or appliance for use with anelectric light bulb socket so that an electric bulb when fitted thereinor carried thereby will be protected or shielded and the light therefromcontrolled or regulated for shading purposes, the parts of the devicebeing assembled in a unique and novel manner.

A further object of provision of a device of this character which issimple in construction, thoroughly reliable and efficient in itspurposes, neat in appearance, readily and easily mounted upon andremoved from an electric bulb socket, strong, durable, easy ofadjustment and fully protective for a bulb and also inexpensive tomanufacture.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and

having a light bulb therein the the invention is the pointed outin theclaim hereunto appendedl V In'the accompany ng drawing Figure 1 is aside elevation of an electric light bulb socket showingthedevice'constructed in accordance with the invention appliedthereto. V a

Figure2 is a view similar to Figure 1 showing the device removed fromthe socket and the same in shifted position. V j

' Figure 3 is a top plan view thereof. Similar reference charactersindicate cor'- responding parts throughout the several views in thedrawing. 1 Referring to the drawing in detail, vA designates generallyan electric light bulb socket of any standard construction and B thelight bulb fitted therein, this bulb being of the usual type. uponand'carried'by the socket A is the guard constituting the presentinvention and here inafter fully described. v I The guard comprises asemi-bulbous shaped reflector or body member 5 having an open side 6through which issues the light from the bulb B. This reflector or bodymember 5 at its smaller end hasa semi-circu lar band 7 bridging theopenside 6 and this band with the companion portion of the member 5constitutes a circular or annular track 8 for guide rollers 9 upon asemi-bulbous shaped shutter or closure 10 for the open side 6 of saidreflector or member 5, the

Adapted to be mounted latter being rotatably pivoted at 11 to the saidreflector or member 5 while the rollers are pivoted to the said shutterto project laterally onto the track and travel upon the same onadjustment of the shutter. Superposed or spaced with relation to thetrack 8 is an annular or circular retaining ring or band 12 which holdsthe rollers engaged with the track 8. Uniting the ring or band 12 withthe track 8 is a series of straps 13 and 14 respectively, these beingjoined with said track 8 in any suitable manner.

The straps 13 and 14 have outbent intermediate portions 15 which providea clearance for the rollers 9' so as not to interfere with the travelthereof upon the track 8. I

The straps let are extended upwardly beyond the ring or band 12 and arejoined with a split ring-like clamp 16 which is adapted to embrace thesocket A and is made firm or fast thereon by a nut carrying bolt orfastener 17 so that the guard will be mounted upon the socket A inproper position to permit the inclosing 'ofthe bulb B and thus guardandprotect the same.

In the use of the device when it is desired to shade the light issuingfrom the bulb B the shutter 10 is-manually turned, thus reducing thesize of the open side 5 and in this fashion regulating the light fromthe bulb as should be clearly obvious. When the shutter 10 is completelyclosed it will obliterate the light rays from the bulb B and thus shutoff the light therefrom. I

The shutter 10 is fittedWithin the reflector or member 5 and its axis ofmovement is upon the pivot 11 for the opening and closing actionthereof, While the rollers 9 guide such shutter when traveling upon thetrack 8 as will be obvious.

What is claimed is An electric lamp guard comprising a pair of semibulbous shaped members, one swingingly movable into the other andtheother constituting a stationary reflector, spaced bands on thestationary reflectorand one constitut ing a track and the other aretainer, straps spacing said bands and having intermediate outbentportions, rollers carried by the swinging member and engaged between thebands and operative upon said track, a pivot connecting the membersremote from the bands and a clamp integrally formed With certain of saidstraps and adapted to embrace an electric light bulb for the securing ofthe reflector thereto.

I In testimony whereof I afiix my signature.
